BED-SPRlNG-COILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 489,550, dated January10, 1893.

Application filed August 4:, 1892- $erial No. 442,152. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE I. STARK, a citizen of the United States,residing at McKinney, in the county of Collin and State of Texas, haveinvented a new and useful Coiling-Machine, of which the following is aspecification.

My invention relates to a coiling machine, designed, especially, forcoiling twin bedsprings in a simple, rapid, and satisfactory manner, andproviding them with the necessary means of attachment to the bed, and myimprovement consists in a certain novel c011- struction and combinationof devices which will be described in connection with the drawings, thenovel features being particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a coiling machineembodying my invention; Fig. 2 is a rear view; Fig. 3 is a side view,showing the removable cone detached. Fig. 4 is a view of a pair of twincoils such as are formed upon my improved machine.

A represents the standard, provided at its top with the bendingmechanism, for forming the points or detents upon the extremities of thewire forming the springs, said points or detents being provided for theattachment of the springs to the bed, and being indicated at I) b, Fig.4, at the lower ends of the springs, B B. Said bending mechanism, 0,comprises a vertical, stationary pin, D, provided with a vertical slot,(1, of a size to receive the wire, and a lever, E, fulcrumed upon saidpin, and provided at an intermediate point with a vertical bending stud,e, rigidly attached to the lever and provided at its upper end, uponeach side, with a notch, 6', also adapted to engage the wire. By placingone extremity of the wire of which the coils are formed in the slot inthe upper end of the vertical pin D, and extending it therethrough farenough to engage the notch in one side of the stud carried by the lever,and then swinging the lever to the right or left according to whichnotch is engaged by the wire, and according to whether a right or a lefthand bend is desired, the end of the wire may be bent to the form shownin the point or detent upon the extremities of the springs, in Fig. 4.

F represents a horizontal shaft mounted in bearings in the standard, atan intermediate point, and provided at its rear end with an operatingcrank, G, the hub of said crank being provided with a ratchet, H,engaged by a gravity pawl, I. The shaft is extended beyond the frontside of the standard and carries a permanent coiling-cone, K, whichtapers outwardly, or from the standard, the portion of the shaft whichextends beyond said cone being squared, as shown, to receive aremovable, oppositely-disposed coiling cone, L. This removable, oradjustable, cone is provided with a squared bore to fit the squaredshaft, the smaller or reduced inner end of the removable cone fittingclose to the outer reduced end of the permanent cone, as shown. Theremovable cone also carries an engaging eye, M, to receive the end ofthe wire which is being coiled upon the cones, toihold the same inposition. Above the shaft, upon the front side of the standard, isarranged a bracket, N, provided with a series of forwardly projectingstuds, of various sizes, and arranged in any desired fanciful design,the object of the same being to provide a former for the intermediate orconnecting portion of the wire, between the spiral springs, saidintermediate or connecting portion being indicated in Fig. 4 by O.

In operation, one end of the wire, which is to form a pair of twincoils, is bent by means of the bending mechanism in the manner abovedescribed, after which said bent end I) is inserted in the eye which iscarried by the removable cone, and the shaft is rotated by means of itscrank to cause the wire to be reeled upon the outer and inner cones,successively. The cones are provided with spirally arranged grooves orchannels, P, in which the wire is designed to lie when reeled thereupon.When the wire is properly arranged in these spiral grooves and extendsfrom the outer end of the removable cone to the inner end of thepermanent cone, the shaft is held from turning by the pawl and the wireis out leaving sufficient material for the other coil B and theintermediate connecting portion 0. The portion of wire adjacent to theinner end of the spiral coil B is now passed around the studs upon theformer, after which the removable core, with the portion of the springalready formed, is removed from the shaft, and the operation, as abovedescribed, is repeated, to form the other spring B.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States, is:

1. In a machine of the class described, the combination with a standard,a rotatable shaft carrying coiling cones, and means to operate the same,of a vertical bracket N disposed upon the standard above said shaft andprovided with forward projecting studs around which to form theintermediate portions of the springs, substantially as specified.

2. In a machine for the purpose named, the

combination with a standard, and a rotatable shaft mounted in bearingsthereon and provided with oppositely disposed coiling cones, one ofwhich is removable, of the bending mechanism, comprising a permanentvertically-slotted pin, and a lever fulcrumed upon said pin and carryinga stud provided at its opposite sides with notches to engage the Wire,all substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signaturein the presence of two witnesses.

GEORGE I. STARK.
